Seven datasets from the federal mortgage record. All free.

The US federal government publishes every mortgage application decision under the Home Mortgage Disclosure Act. The raw file is roughly two gigabytes and effectively unusable without processing. These datasets are that processing, released openly: computed with published rules, reproducible from the public source, and licensed for any use including commercial, with attribution.

Load any of them in one line:
from datasets import load_dataset; d = load_dataset("FinanceRateCalc/fha-denial-rates-top-100")

Permanently archived at Zenodo with DOI 10.5281/zenodo.21575105 — the citable, version-stable reference for this collection.

Why these are free

Because the people who need this data most are the ones least able to pay for it. A borrower who was refused a mortgage, a first-time buyer choosing between lenders, a local reporter, a housing counsellor, a graduate student — none of them are going to buy a trade subscription. The underlying record is public and was collected at public expense; the processing is the only thing that was missing.

Attribution is the only condition, and it is a real one: open data that circulates without provenance stops being verifiable. Suggested form: Primary data: CFPB HMDA. Derived rates: FinanceRateCalc (Yetiş, 2026), financeratecalc.com

Reproducibility

Every figure can be recomputed from the raw CFPB file using the rules at methodology. Denominator construction — which application outcomes count as decisions — is the single largest source of divergence among published mortgage denial statistics, so ours is stated explicitly rather than implied. Where our figures differ from another publisher's, the denominator is usually why.
